- Abstract: Objective To investigate the analgesic effect of ultrasound-guided quadratus lumborum block combined with patient-controlled intravenous analgesia after lower abdominal surgery.Methods A total of 134 patients who underwent lower abdominal surgery in General Hospital of Central Theater Command from April 2021 to April 2024 were prospectively selected and randomly divided into the observation group and the control group,with 67 patients in each group.Patients in the observation group received ultrasound-guided quadratus lumborum block combined with patient-controlled intravenous analgesia.Patients in the control group underwent only patient-controlled intravenous analgesia.The number of analgesic pump compressions and the cumulative sufentanil consumption 4 hours,6 hours,12 hours,and 24 hours after surgery,the visual analogue score(VAS)of pain at rest and exercise,and the incidence of adverse reactions during postoperative analgesia were compared between the two groups.Results Compared with the control group,the number of analgesic pump compressions and the cumulative sufentanil consumption of patients were fewer/less at 6 hours,12 hours and 24 hours after surgery in the observation group(P<0.05).The VAS scores of patients at exercise 4 hours,6 hours,12 hours and 24 hours after surgery in the observation group were significantly lower than those in the control group(P<0.05).The incidence of nausea,vomiting and vertigo in the observation group was significantly lower than that in the control group(P<0.05).Conclusion Compared with patient-controlled intravenous analgesia,ultrasound-guided quadratus lumborum block combined with patient-controlled intravenous analgesia can significantly reduce the number of analgesia pump compressions and the cumulative sufentanil consumption in postoperative analgesia of lower abdominal surgery,and has a better effect in relieving exercise pain,it can also reduce the occurrence of adverse reactions such as nausea and vomiting.
